Question

What is the specific heat of copper if a 75 g sample is heated from 20°C to 24°C by adding

117 j?

Answer 1

Specific heat capacity of the copper is given as

`s = 0.39 J/g ^oC`

Step-by-step explanation:

As we know that the heat required to raise the temperature of the given substance is given as

`Q = ms\Delta T`

here we know that

`Q = 117 J`

mass of the given part is

`m = 75 g`

change in temperature due to heat supply is

`\Delta T = 24 - 20 = 4^oC`

now we have

`117 = 75 (s)(4)`

`s = 0.39 J/g ^oC`
